When diagnosing CPU performance issues, CPU Ready Time and CPU Usage are the key indicators of whether more vCPUs are needed.
* Option A (VM CPU Ready Time) is correct:
* High CPU Ready Time means the VM is waiting for CPU resources, indicatingCPU contention.
* Option B (VM CPU Usage) is correct:
* If CPU usage isconsistently high, adding more vCPUsmay improve performance.
* Option C (Host CPU Usage) is incorrect:
* Host-wide CPU usage does not indicate whether a specific VM needs more vCPUs.
* Option D (Host Memory Swap Out Rate) is incorrect:
* Memory swappingaffects RAM performance, not CPU allocation.
